A further object of the invention is .the pro-- vision of an improved cylinder lock having an,

known type and their'skeepericontml need not be no.

The improved lockA preferably includes 'a rotatable cylinder ilock casing C having-operas tivefly associated therewith aj-rotatable' plug D. Tumbler mechanismE is associated with the easing C and plug D, controlled as to position by so means of a key F which isinsertable into a key slot in theplug D, to permit relativerotation of the said plug D in :the cylinder casing .015 in associated relation with the cylinder-dis a re,- movable memberGof cap-like formation-Which 6'5 acts'as a hand hold to facilitate turning ei the cylinder casing C1; the ipartsC andG being fixedly connected together atlall times. The closure .01" other support Bis provided withja sleeverlike keeper .or hub H, in which the -rotatablegportions of thelock mechanism are supported, for rotation.

The lock .casing C, as above mentioned, :is; .of x cylindrical construction. :A:|3 :its inner .end .it is '80 axially provided with a reduced polygonal shaped projection 30, integral with the EbOdyaOf :theoasing C, and a :fnrther'reduced axially extending 'externally .:screw :threaded shank 3=1... The:bo'lt mechanism L is adapted 3110 he Ereceivedonthe '85 portion ,30'. It consists of a :body :32 :having a squared opening therein which will snugly vreceive the extension 30 in order .to directly key the body 232 for rotation with the cylinder The body 32 is .of "the same thickness. as .the extension 3.0 and abuts-againsta shoulder 3.4- at theinner end of the :body .of .:.the ..cylinder lock casing A washer .135 :is slipped .over the shank 3 l and ;a nut 36screwed on the latter for clamping the washer 4 a ainst the =-body 32 of :the bolt :mechanism in order to, prevent thev ilatter from flailing .off the casing C. .p

The body portionv 320113118 Joolt mechanism L mayhe of any :approced nature; ltrisnreferabl of the three-way bolting type, such as used :up n 1 locker .doors, safe .doors, and iballot and Notin machine. boxes. To :that end it is nreierably rovided with ,a radially extending sloshin 111 40,1i3J1d at 190 theretd and in :relativ iametri l cally opposed relation, :there are also. p ovided 1 05 radialextensions 421, and .42 :to whiehl chingsbar or arms :44 andi5 are respeotivelypivoted. These looking .bars or arms :44 and 4,5 arernfrthe-weflfurther described.

The closure or other support B which rotatably supports the lock mechanism is provided on theinner surface thereof with the hub H which serves as a rotatable support for the' cylinder lock, and also as a keeper for the locking plunger K. This memberH includes a cylindrical body portion 46 which at one end thereof is provided with preferably four radially extending lugs .47 apertured at 48, as shown in Figure 7, and adapted to receive rivets 49 for bolting the same upon the inside of the closure or other support B. The

latter isprovided with an opening 49 therein, and the hub or member H is provided with an annular lip extension'SO which projects into the support opening 49, as shown in Figures 2 m 8 of the drawings. The hub or sleeve member 46 is provided with an outwardly facing socket 5 1 which terminates in an annular shoulder 52 ar- The cylinder lock casing C is, of .course, of cy-v lindricalformation for rotation within the support attached hub or'sleeve member Opening on its'outer end it is provided .with the plug socket therein, which terminates in a dead end 61. The .lockingplug D is rotatably received in this socket 60; the said lockingiplug D including. a

eter, which, at, the outer end is provided. with an annular flange head 64; ,At its inner end, short of the; dead end 61 the plug D is provided with a rigid'e'ccentric cam extension'fifi. The locking plunger or member K is slidablysupported in 'a passageway 68 providedradially in the lock 'cas-. ing 0' thereforrthe passageway 68: intersecting thev rear end of the plug :socket 60 and opening radially at one point on the casing. The, hub member. or look support sleeve I-I' is provided with a keeper. opening71 adapted to receive the end of the locking plunger K- .The latter is pro vided. with a lateralopening74 which receives the eccentric 'cam extension 66 therein. Thus, as the plug Dis rotated the plunger K will be moved into, and out of the keeper opening or socket 71, that is, when thev parts. are properly positioned for-such action. I. r 3

The movement'of the plug D is limited to a turn of'approximately' in order to enable-the locking plunger K to be .thrown into full locking and full retracted-relation With" respect was This angular movement of the plug D in the cylinder-C: is:controlled by means ofa set screw 80, shown'inFigurefi, which is detachably carried by theicasing C, -and which has an inner reduced endprojec'ting into: a slot 81 which'is circumferentially recessed into the plug D, near the inner end of the latter, for a distance of about '90 or more. i

The tumbler mechanism E is of the usual type, and need not be. further described except tion by means of the cap G, in lieu of the usual metalslide which is additionally provided therefor. This cap G includes 'abody portion 90-having a socket 91therein which receives the-outer end of the cylinder casing C. The innerend 92 of the'cap body 90 is reduced; and :fits into the enlarged portion 51 of the passageway-through the hub or look supporting memberH; the annu lar shoulder 95=at the juncture of "theareducedl.

portion 92 with the body 90 of th'e ca'p G'abutting.

not be withdrawn.

and overlapping in a secreting relationthe outer 49 and also overlapping the marginal portion of the closure or other support B which surrounds the opening 49 in order to secrete the joint.

The cap or member G, is rigidly connected with the casing C, although in a removable manner, by means of countersunk set screws 98, shown in Figure 4 of the drawings, which are mounted in openings in a reduced inner end 92 of the member G, and thus secreted in the hub H when the lock is in position. The cap G is provided with an outer annular wall which covers the outer end surface of the cylinder lock casing C, and which vhas an opening therein snugly and rotatably receiving the head portion 64 of the plug D; as shown in Figure 8. It will be noted from Figures 2. and 8 of the drawings that the cap G receives the entire portion of the casing C- therein upon which the tumbler.mechanism is mounted, so that the springs of the tumbler mechanism are retained by this cap.

The'relation in which'the cylinder lock may be turned in the sleeve lock support H is limited for a proper throw control of the bolt mechanism L. This is accomplished by'providing a.

which has a reduced end 106 projecting into a slotv 107. The latter is recessed for a short distance circumferentially about the outer surface of. the cylinder lock casing C, in order that the casing may be thrown for a turn which will enable the bolt mechanism L to be drawn into or out of position with respect to the keepers (not-shown) provided therefor.

From the foregoing description of this invention it is believed the operation and control of the locking mechanism will be apparent. In order to unlock the bolt mechanism L for access to the container upon which the lock mechanism is used,

the key F is inserted into the position shown in Figure 2, forproperly positioning the tumblers of the tumbler mechanism. Upon turning of the keyF to the right, for a short angular turn,rthe plug D will be rotated, and through its cam connection with the plunger K the latter will be withdrawn from the keeper socket 71, to the position shown in Figure 8 of the drawings. The cap G is provided with'diametrically opposed handle extensions 110 which may then be grasped by the operator and the-entire cylinder lock casing, together with the cap G' and key mechanism thereon, may be rotated for throwing the bolt mechanism L to an unlocked position. It will be noted that so long as the plunger K is in the unlocked position shown in Figure 8, the key F can- --Various changes in the shape, size, and ar'-' rangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the 4 vactuatingcam carried by the plug, tumbler mech-i anism in said passageways of the cylinder casing andplug for controlling rotation of the plug with! in the cylinder casing, and a caprigidly and removably anixed upon the outer end "of the cylinder 'casing'with the latter. in a'secreted relation therein, said cap overlying and holdingthe tumbler mechanism in position in the said passageways and having a front wall secreting the cylinder casing and provided with an opening therein exposing the outer end of the plug,
